Answer:
the angle, in radians, between the central maximum = 2.87degree or 0.05radians
Explanation:
The detailed steps and appropriate formula is as shown in the attachment.
Using λm = dsin teta
where d =20λ, m = 1
from the formula, sin teta = λ/20λ
= sin teta = 0.05
teta = arc sin(0.05) = 2.87 degree
This is Kinematics and the equations in your book.
A speed time graph would plot the speed of something against the teime it was at a speed.
If it were changing it speed constantly, that would be a straight line if acclerating. Total distrance would be the area under the graph.
The solutions would be :
1. C
2. B
3. A
4. C
5. D.

Answer:
The rms voltage (in V) measured across the secondary coil is 459.62 V
Explanation:
Given;
number of turns in the primary coil, Np = 375 turns
number of turns in the secondary coil, Ns = 1875 turns
peak voltage across the primary coil, Ep = 130 V
peak voltage across the secondary coil, Es = ?

The rms voltage (in V) measured across the secondary coil is calculated as;

Therefore, the rms voltage (in V) measured across the secondary coil is 459.62 V
